The Giant Crab Spider is one of the
largest spiders you'll see in the deserts of the southwest. It has a
body to 1" in length or more and a leg span to 3". It's
color is light brown with a
dark, Y shaped marking on the top of its abdomen and dark fangs in
front. Like other crab spiders, it often holds its legs at right angles
to its body.

Natural
History

This spider occasionally is seen on walls
or ceilings of houses (unlike
wolf
spiders and tarantulas that do not climb). The giant crab spider walks
around in search of insect prey at night, but usually hides during the
day. Despite its appearance, the giant crab spider is not dangerous to
humans (though the bite can be painful).

Crab spiders get their name by
their ability to rapidly move sideways, like a "crab".

Giant crab spiders are found throughout Arizona and
Sonora in a variety of habitats including: in dead saguaros, under rocks
and in homes.
